BY Kim [6761/ 7 ATTORNEY United States Patent 3,188,772 LOCK BALL ROOFEDGING Alfred A. Tennison, .lr., P.0. Box 7, Texarlrana, Ark. Filed Nov.3, 1961, Ser. No. 149,901 4 Claims. (Cl. 50-66) This invention relatesto buildigs and other structures having upright, horizontal, and othersurface portions disposed at various angles and including equipmentemployed in the production or fabrication of certain parts of suchstructures and of various kinds and from various types of materials.

This invention relates particularly to roof or other structural edgingor trim, applied during or subsequent to the construction of a buildingor other tructure, for providing durable weather or moisture excludingjoints and finished portions along horizontal and inclined edges.

Finishing trim or edging has been provided for unfinished edges of thekind indicated and especially for the edges of roofs but theinstallation of the same has been by telescoping them end to end or in amanner requiring more than a single workman and accordingly has beenexpensive.

It is an object of the invention to overcome the ditficulties enumeratedand to provide a finishing edge or trim applicable to the edge of a roofor other structure, and which edging or trim is of simple andinexpensive construc-tion, can be readily manufactured and applied tovarious types of structures including to a roof by overlapping andfitting together endwise the end portions of two lengths of such trim,rolling one relative to the other already fitted in place and secured tothe roof and applying fasteners to such other or second rolled member.

Other objects and advantages of the invention will be apparent from thefollowing description taken in conjunction with the accompanyingdrawings in which:

FIG. 19, a section illustrating one application of the structure of FIG.18.

Briefly stated, the edging or trim of the present invention intended tobe applied to roofs and other structures includes a generally flatportion adapted to lie snugly upon the surface of the roof or otherstructure, with a ice portion adapted to fit around the edge of suchroof or other structure substantial-1y at right angles to the firstsurface, and with means for securing the same in place including agenerally circular portion opposite the generally flat portion with theextremity of such circular portion disposed at an angle to permit theapplication of a length of such trim and then the application of asecond length in overlapping relation by the application of the secondrelative to the first in such overlapp ng relation, and then rolling thesecond length to its final position thereby providing a locking jointand a finishing trim of multiple lengths and resulting in an improvedappearance, exclusion of the weather, and increase in the life of thestructure in the location of the trim.

With continued reference to the drawings, five forms of the inventionare illustrated, the first appearing in FIGS. 1 to 6, the second inFIGS. 7 to 10, the third in \FIGS. 11 to 13, the fourth in FIGS. 14 to17, and the fifth in F168. 18 and 19.

In the embodiment of the invention illustrated in FdGS. l to6 a buildingor other structure is provided including siding 11.0 with root sheathing1-1 with a lower or outer edge v12 upon which is applied an edging ortrim designed to improve the appearance and to aflFord protection.

The edging or trim has a flat portion 13 adapted to lie flat upon thesurface of the sheathing 11 or other structure and to be secured theretoby nails'or other fasteners 14. The edging or trim has, integral withthe fiat portion 13, a generally right angular portion 15 with acircular or rolled portion 16 at its lower extremity and terminating ina flange 17. The circular or rolled portion 16 is in spaced relation toand underlies the flat portion 13 in order to receive and clamp the edgeof the sheathing between such flat and rolled portions and to presstightly against opposite sides of the sheathing due to the spacing ofthe rolled portion from the fiat portion slightly less than thethickness of the sheathing causing a spring type action between itsoverlying .and underlying portions. v lo intimate relation thus providedbetween the trim and the sheathing eliminates air spaces between thetrim and the sheathing for the accumulation of moisture, bacteria orother undesirable matter.

The trim described may be made in a continuous length eliminating thenecessity for a transverse seam however, where desired it can be lappedFIG. 3 with additional trim of like nature. FIGS. 4 and 5 illustratesthe method of overlaying two trim members to form a locking joint FIG. 3when in place about the edge 12. of sheathing 11.

Each end of the rolled portion 16 has a tapered angular portion 18providing means for interlocking adjacent lengths of trim. In order toform a lock the worker rotates the length of trim being attached to aposition substantially from its attaching position and slides suchlength along the sheathing until the tapered portion contacts thetapered portion of a length of trim which has been attached to thesheathing. The length of trim being attached is then rotated to itsattaching position, during which rotation the tapered portion of theattached length of trim will function as a cam. As illustrated in FIG. 3a shallow V-shaped opening may be formed by the overlapping taperedportions of the contiguous rolled portions and such opening will providea drainage opening for the discharge of water trapped therein. When thecontiguous lengths are in assembled relation the tapered portions arelocked together to provide mutual support at the joint.

In FIGS. 7 and 8 a generally similar trim is provided including a fiatportion 2% with an upstanding ledge 21, and portion 22, and a curvedportion 23 corresponding to the portion 16 of the proceeding figures forgripping the underside of sheathing 11, also the ends of curved portion23 are angled the same asportions 18, FIG. 6. The ledge 21 is includedin order to provide a stop or retaining ledge for a conventional cover,which could be of individual parts or a unitary structure.

'In FIGS. 11 to 13 a trim resembling the trimof FIGS.-

flat plate 30 is provided which corresponds to the flat plate13 of FIGS.1 to 6. However, the edge of the plate is provided with a drainage lip31 connected by a strip' 32 forming a ventilated portion between theupper and lower edge of the outer edge 12 of sheathing 11 with thereversely contained portion 33 having a terminal flange 34 forstrength'and adapted to engage and bite into the underside of thesheathing 11 at '35;

In FIGS; 16 and 17 instead of the flat portions 32 and V 33 the flatsheet 36 has a reversely bent portion 37 pro- Y viding a .drip ledge 38.The structure also has connected to the reversely bent portion 37 aright angular portion I 39 with the reversely contained portion 40 andan angular portion 41 with a terminal portion 42 adapted to en-' gageand bite into the opposite sideof the sheathing ll from the plate 36. a

In FIGS. 18 and 19 a somewhatsimilar structure is provided as that shownin FIGS. 16 and 17 except that the sheet 46 is adapted tounderlie andretain other mat-. ter, not shown. The sheet 46 is providedwith a flange47 at one edge and a retaining lip at its other edge formed by providingthe plate with an upward bend 48, a reverse right angular bend 49 and asecond reverse bend 50. To the second reverse bend 50 and integraltherewith is aright angular portion 51 adapted to extend over the end ofthe sheathing 11 and then bent rearwardly at right angles to provide aright angular portion 52 bent to provide a portion 53 at an acute angleand a portion 54 parallel to the sheet 46 for receiving the sheathingtherebetween;

It will be apparent from the foregoing'that the present inventionprovides finishing trim appropriately applicable in one. or more units'or lengths, Jsuch trim including a cover plate portion designed to beplaced upon the marginal area of a structure, with an' integralgenerally right angular portion which extends around the edge of themarginal portion, and with a resilient portion underlying the flat coverportion in opposed relation thereto to provide a clamping action forsecuring the trim in place,.and due to the angular construction of theend portionafter a trim unit has been applied a second unit can beinstalled by a single individual by disposing the second unit with itsend overlapping and fitting together withthe end of the first unit andthen rolling the second relative to the first causing the two units tobe locked together and due to the clamping action on the sheathing veryfew fasteners will be required for permanently securing the units inplace.

It will be understood'from the foregoing that in the production of theinvention anyof the designs illustrated may be employed and the topsurface portions, the terminal portions and *gnipping portions may beselectively combined. I I

It will be obvious to those skilled in the art that various changesmaybe made in the invention without departing from the spirit and scopethereof and therefore the invention is not limited by that which isillustrated in the,

drawings and described in the specification, vbut only as indicated inthe accompanying claims.
